Atmospheric/Air Pressure: Atmospheric pressure has a direct relationship with atmospheric temperature. This means as the atmospheric pressure increases, atmospheric temperature also increases with it, and vice versa.

Altitude: Temperature decreases as the altitude increases (and increases as the altitude decreases). This explains why it’s freezing cold in the hilly regions (with higher altitudes).

Humidity: Humidity is, in simplest terms, the water vapor content in the air. As the humidity increases, temperature also increases. This explains why there is hot, uneasy weather after raining.

Angle of Sunlight: Sun’s radiations hit the different parts of the earth surface at different angles. The part that receives direct sun rays- the equator-is the hottest, i.e. highest temperature. Temperature decreases with slanting rays, and so poles have low temperature.
